Kesto (234.48:4), released jointly by Blast First and Mute Records, is the fifth album released by Pan sonic. The Finnish title roughly translates to « strength » or « duration », referencing both the quadruple-disc album and the general abrasiveness of their music. The subtitle « (234.48:4) » is the length of the entire album. Each of the discs are in slipcases with photographs by Anne Hämäläinen gracing the covers.
